Definitely nothing switched onTick over speed ina vehicle tends to rise if an electrical device is switched on.
In most cars this is easy to observe by running at tick over and switching the heated rear window on.
Are you sure you are not observing tick over with a device that is sometimes off and sometimes on.
Possible suspects are
the fridge on 12v
a B2B device;
some form of heating (seat windows mirrors rather than habitation) .
Dose it flag up on dash re gen progres ?? .Check it is not going through a DPO filter regeneration, this will increase your RPM
No when my van is going through a dpf regen the reeves go up to a 1000rpm where normally it ticks over at 800Dose it flag up on dash re gen progres ?? .
When mine did that it was the accelerator pedal and I had to have it replaced it started just with a faster tick over then in a few days it would just rev up for no reason when at traffic lights or as you say when just driving normally.First noticed the problem going round a roundabout , foot off the accelerator then van picked up speed as tick over increased ,
Yes they should be able to see what the alternator is putting outCould this be picked up on a diagnostic checķ

Yes and I still owe you a dept of gratitude because you found me the accelerator pedal as I was stuck in Scotland when mine went.This was the problem that I had Annie, I still carry a spare accelerator pedal, how sad is that
A few threads about it, it should show up on a diagnostic check even if it didn't put the warning light on
Including one where Barry suggested it could be the fly by wire
